Application led May 27, 1912. Serial No. $219,958.

To all whom t may concern:

Be it known that I, WILLIAM J. NEIDIG, a citizen of the .United States,residing at Madison, in the county of Dane, State of IVisconsin, haveinvented a certain new and useful Improvement in Type-'Writing Machines,of which the following is a speciiication, reference being had thereinto the accompanying drawings.

Certain principles and features of my invention as described herein areincluded within the invention which is described and generically claimedin my co-pending application tiled April 20, 1908, Serial No. 428,212. y

One of the objects of my general invention is to indicate to theoperator of a typewriting machine the decreasing distance from thecurrent printing point to the bottom end of the sheet, or to anotherpoint on the sheet, during the progress of the sheet, and this withoutpreliminary care on his part, automatically. This function I believe hasnever before been performed, but is novel to my generic invention.

Additional objects are to supply the operator with other indicatingmeans, comprising improved visual, audible and machine-lock .signalsgiven sheet-positions.

The present embodiment o-f the invention has as features certain novelco-mbinations of sheet-controlled elements adapted to render theinvention more useful under the va.- rious conditions of practice, aswill be explained. l

In the drawings,-Figure 1 is a side elevation of portions of atype-writing machine carriage, partly broken away, showing my inventionas applied thereto, certain portions of the main frame also beingindicated. Fig. 2 is a plan view of some of the parts shown in Fig. 1.Fig. 3 is a crosssection on the line 8-3 of parts shown in Fig. 4. Fig.4 is a view chieiiy in section on at predetermined the line 4-4 of Fig.3, looking in the direction of the arrows, and showing the drivemechanism actuating drum 6. Fig. 5 is a side elevation of a portionof atype-writer carriage showing a modification. Fig. 6 is a pian view ofthe same. Fig. 7 is a side elevation re resenting another modification.Fig. 8 is a ront view of the same, the carriage being shown in section.

Referring to the drawings, the main frame of the machine is indicated at4.1, and. the-usual carriage frame, movable laterally as in practiceupon the main frame, at 12. In the carriage frame at either .end isjour'- naled platen arbor 13, which bears fixedly attached thereon inusual manner the typelwriter platen 10, whicl: A:s herein regarded isthe principal feed-rci4 for feeding the sheet through the machine. Theplaten is .connected as in practice with usual linespacing mechanism,not shown herein, of any approved type. The paper-table for the supportof the entering sheet is'shown at 8, the same being carried in usualmanner upon carriage-frame 12. This structure is well-known to tho-seskilled in the art and need not be more fully described. Against theplaten head 39 at the end of platen 10 is aiiixed inner shell 11 so asto rotate in unison with said platen head` and therefore with the platento which the platen head is attached. Independently journaled uponplaten arbor 13 is drum 6, the laterally extending peripheral portion ofwhich over laps inner shell 11 and moves loosely' thereon. Drurrai 6consistsof a peripheral or index-bearing portion, an upstanding portion,and a bushing portion, the upstanding portion being iXedly attached tothe bushing portion 6. Upon the inwardly projecting pins 53 on said drumare journaled the belllevers 18 connected by means of the pins 1G withthe friction-pieces 5. Springs T attached at one end to pins 4 on'saiddrum en-A igage at the other end with said bell-levers sleeve 21.Fixedly attached to said sleeve near one end is stop 15 and Xedlyattached near the other is paper-feeler 28, the parts. being so mountedthat a short slot or opening 4 in paper-table 8 lies underneath thepaper-feeler, and the end of stop 15 lies in the vplane of projection14. The spring 151 tends to move stop 15 out of the path of saidprojection and paper-feeler 2B into said slot, one end of said springbeing attached to carriage frame 12 and the other end engaging upon saidstop. Carriage traine 12 bears also the inwardly extending pin 22, onwhich is journaled hub 23 bearing hammer-stem 24. Lever 25 having aweighted portion 31 is also journaled on pin 22, but outside of theplane of projection 14 on the drum. Lever 25 bears the pin 29, whichengages upon said hammer-stem. An outwardly extending pin is carried bydrum 6 in such radial position as to engage with lever 25 but not toengage with stop 15. Pin 36 may be screwed into any one of the threadedholes 30", so as to engage with said lever earlier or later. Stem 24bears bell-hammer 26 ailixed to the free end thereof, and is given aU-form, downward, outward and upward, for convenience in bringing itadjacent to the bell 27, supported from carriage frame 12 on central pin32. Carriage frame 12 bears also the inwardly extending pin 40, on whichis journaled hub 72 having a downwardly extending portion 43, a jointedlever-portion 1, and a leverportion 45. Said downwardly extendingportion 43 and pin 40 may be regarded as 'representing similar parts onthe carriage frame at the opposite end of the'platen, as will beunderstood, the said parts 43 being joined by the laterally extendingpart 42 so as to form a rocking bail-piece. The portion 42 of'thisbail-piece is supplied with teeth 44 alternating with interdentalspaces. Attached to the carriage track about midway laterally betweenthe stationary frames '41 of the machine is the stop 48 having atoot-hed portion 49, the arrangement being such that when bail 42is'rocked rearwardly on axis 40, teeth 44 will pass on either side oftooth' 49. Lever 45 is continued rear-r 'wardly, and rests by gravityagainst stop 47 bon carriage frame 12. Lever 1 is mounted in such aplane as will not engage it with projections 14 and 30 aforesaid.Coperating' with said lever is projection 68 which *may be screwed intoone or another of the threaded holes 68 in the upstanding portion ofdrum6 so as to be angularly adjust.- able on said drum. It will beunderstood that pin 68 has a radial position permitting itto clear lever25 and stop 15.

The action of the mechanism is as follows: The sheet of paper 33 isplaced upon the paper-table 8 inusualinanner and advanced toward theplaten for entering into the machine. This act-ion carries the leadingedge lof the sheet'under paper-feeler 28 so as to -raise saidpaper-feeler out of slotv4, the paper-feeler being light and suitablyshaped and moreover projecting into the slot only a -short distance.This action rocks sleeve 21 and moves stop 15 upwardly until it lies inthe path of projection 14, against the action et the light spring 151.All these parts are constructed as light. as possible so as toreducerinertia, and the spring-action is extremely light. It is found inpractice that by such use of the leading edge of the sheet the operatoris able to move the lightly poised stop 15 into the path of projection14 without the exercise of additional care. The sheet will be advancedthro-ugh the machine by the platen as usual. The turning of the platencauses drum 6 to rotate, frictionmember 11 being in engagement with thecooperating friction-member 5 and acting drivingly thereon. Thisrotation of drum 6 will eventually bring projection 14 against stop 15in its path. Drum 6 will thereafter be maintained in a stationaryposition during the presence of stop 15 in engagement with projection14, and in this position it will remain until. the .bottom end of thesheet passes from under paper-feeler 28. Upon the passing of thesheet-end, paperteeler 28, no longer controlled by the sheet, and underthe actuation of spring 151, will enter slot 4, and stop 15 will bewithdrawn from the path of projection 14. Drum 6 under its frictionalactuation will now be given movement simultaneous with that of theplaten. I V

Since the end of the paper-feeler 28 must intersect the paper path sothat the paperfeeler is always released when the end of the sheetisaiixed distance from the printing point, drum 6 mustfbegin itsmovement when the bottom edge of the ,sheet is a fixed distance from theprinting point, and as the drumv maintains .always a line by lineprogress thereafter with the sheet, since it moves with the platen andthe platen advances the sheet, it must bring always the same po-int onits periphery oppo-site pointer 34, attached to carriage frame 12, -whenthe end of the sheet attains any given distance from the printing point.This distance, .whatever it be, can be determined, and can be indicatedby an index on the drum or index-carrier 6, so thatthe distance from theend of the sheet to the lprinting point will be indicated step by stepfrom the time paper-ee'ler 28 is released by the sheet until the sheetleaves the machine, or as lo-ng as desired. The kind of indicesemployed, and thevunit of measurement, will be as may be preferred. I

prefer to use numerals for indices, arranged in descending order asshownin the drawing. It is ot' course 'immaterial whether the movable indicescome to rest exactly opposite the stationary index or pointer, orwhether the indices in themselves signify distance units, or indicate.the entire remaining distance to the bottom edge of the sheet or onlypart of it.

I usually employ for a stationary index a v'shield-pointer, thatconceals one portion of the carrier from the operator, and the carrieritself is divided into two different-api bij sheet.

pearing segments, one of which is visible to the operator during thedetained position of the carrier, and the other of Which is not visiblebut lies behind the shield-pointer in that position of the carrier. Inmy drawings I show the first named of these segments as containing noindices except the circular index 89, and by preferencel I color thissegment black, and the second of these segments, which I cause to bearindices, I prefer to'supply with a ground of White. When the sheet endreleases the carrier or drum, and the White index-bearing segment comesinto view, the change from black to White attracts the operator-sattention and he knows that the end of 'the sheet is Within a givendistance from his printing point. It is not essential that the Whitesegment should come into view at the very first feedmovement after therelease of the carrier.

` My audible and machine-lock `signals are given as follows: Atthepredetermined time after the release of drum 6 to move with the platen,projection 30 engages with lever 25, rocking the same upon pin 22 andthrough the engagement of project-ion 29 upon hammer-stem 24 moving thebell-haii1 mer 26 from bell 27 until pin 30 clears lever 25,Whereupon'hammer 26 falls by gravity against bell 27l and gives theoperator an audible signal as to his sheet position. My machine-locksignal `is given as follows: At the predetermined time, project-ion G8engages with lever l, thereby pressing lug .71 against lhub 72 androcking said hub and the attached bail-piece 42 upon pin 40 until teethMare brought into engagement with tooth 49 on the machine frame. Thecarriage is thereby locked against lateral movement, the typewritermechanism rendered inoperative, and the operator warned that itis timeto remove his In case he should desire to print. another line upon thatsheet he has only to turn his platen forwardly until lever l is releasedby pin 68 and then backwardly into the 'desired line position. Thepart-s on pin l0 will instantly return by gravity .into the positionAshown in Fig. l, releasing the machine for further use.

Itvvill be noted that the mechanism described can be backed up from anyposition and to any required extent. Stop l'is constructed-With abeveled head and with a double bend or offset in the shaft portionthereof. In case of bacltward actuation of projection 14 against stop l5during the presence of the sheet under the paper-feeler, stop l5 willlift and permit projection le to pass thereunder, and when theprojection comes to the oiiset portion of the stop the stop will bereleased by the projection and return intodetaining position. Backinguipof projo ion 30 past-lever 25 is provided tor through the givewayengagement of pin 29 upon hammer-stem 24, said parts separatl ing insuch a movement and the Weighted portion 3l of said lever returning theparts into position after the passing of said pro jection. Backing-up ofprojection 68 past lever l is provided for, lever l bending backward onpin 7l, lug 70 separating from hub T2 so as to permit of the action.

I usually station my paper-feeler over the paper' table 8, and usuallyso ,mount the inciding with the plane of projection 14, but the positionand form of these parts may vary, as may the speciiic form of meansemployed to give the iiidex-oa.rrier or drum movement after its releaseey the stop. In the Figs. 5 and 6 I show a typical inodica` tion in themanner of mounting the feeler and stop part-s referred to. Theindex-carrier 6a and its frictional driving mechanism are es'-sent-ially the same as described hereinbefore. The platen head 39a ishere made thicker in order to hold the'carrier farther away from the endof the platen and give room for the vaction of the parts. Attached tocarriage frame l2 is frame-extension Ll2 bearing pin A 20a journaledupon which is bell-lever Se. One arm of said bell-lever has attachedthereto the. paperfeeler 28 having action into slot 4.- in paper table8. The other arm of said bell-lever is mort-ised. Pivoted in the mortiseby means of pin 20d is stop 15a, lugs 62 and 63 limiting the movement ofthe stop upon said pin. A spring 152, one end of which engages upon saidbelllever and the other end of which is attached to frame- .extension42, tends to roclr said bell-lever so that stop 15R takes a position outof the path of projection 14a and paper-feeler 28,a a position 'in slotIl. 1When the paper sheet is enteredl down' paper table 8, the leadingedge thereof raises paper-feeler 28a out of slot 4,

thereby'moving stop lo into the path of projection '14, In this positionthe stop eooperates With the said projection to stop 'carrier 6a. Whenthe end of the sheet passes the paper-feeler, stop 15e is Withdrawn fromprojection lll by theaction of springA 152 and the carrier thereuponbegins its movement with the platen and thereafter performs itsindicating functions, Whioh are identical with those. of carrier 6 oftheearlier figures. y

In Figs. 7 and 8 I show how the pap'erfeeler may be mounted underneaththe platen. Attached upon carriage frame 12, is frame extension 48supporting the tivo ends of pin 20". Journaled upon said pin esv llfi

is sleeve 2la having tixedlv .attached thereto near one end the lever64a and tixedly attached thereto near the other-end the lever 152. Lever6l has attached thereto at its free end the upwardly extendingpaperfeeler 28a, having a path into the circumferential slot ft in theplaten. Lever l5 is 75 parts that stop l5 will move in a plane covjournaled on pin 20c and having a lug 62 to limit its nmvement on saidpin. Said stop is supplied with an ear 5l .tor one end o'l' spring 153,the other end ot the spring being attached to pin 55 on trame-entension12S, said springtendingto pull said parts together. Normally the partsasslune the position shown in Fig. 7, with the paper-teel-er projectinginto slot eta and stop 15b maintained ont. of the path of projection 14,spring 153 givingY the parts such position. The sheet entered as usualinto the machine. Vvlhen the leading` end thereof encminters paperfeeler28 it lifts said paper-teeler out of the paper path and moves stop 15binto t-he path of projection 14, which eventually will be stopped or-detained thereby as before. Upon the passing ot' the sheet-end thepaperteeler will enter the slot, stop 15b will be retracted fromprojection 14 by the spring, and carrier 6 Will begin its movement withthe platen, as before, and perform its indicatingr functions. Backing-upin these modifications is provided for. In case of stop 15n of 5 and (3,projection 1l lifts the stop out of its path, the lug 62separating-t`rom lever G4 and permitting the movement. In the case ofstop 15b in .Fins. 7 and 8, essentially the same Q action occurs, lug62a separating from lever 15 when the projection 1s backed againstsaid'stop and permitting; giveway movewill be switched into an openby-path out over the top of the feeler. In the embodiments shown inFigs. 5 and 6 the backingup bottom edge oi' the sheet will lift thepaper-fecler out of its slot just as the leading edgewvill do when thesheet is entered. lt is to be noted also that in practice an operativemember like drum G that is given movement with the usual abruptlystarting,r and stoppingv platen tends to creep or drift in line-spacedirection lrelatively to the platen, and that the 'friction-drive.herein shown is especially adapted to check any such tendency, suchmovement on the part of the member acting; togglenvise to increase thefriction between the member and its driver. j
